Influence of annealing on the tribological properties of Zr-based bulk metallic glass

Annealing regulation plays an important role in improving the mechanical and dynamic properties of bulk metallic glass (BMG), but the influence of annealing on the tribological properties of Zr-based BMG hasn't been investigated. In this study, we comparably investigated the tribological properties of the Zr-based BMG (Zr61Ti2Cu25Al12) under different annealing degrees. The result shows that the anti-friction property of the BMG weakens with the increase of the annealing degree, but their anti-wear property presents an opposite trend. This study makes a contribution to understanding the relationship between the annealing degree and tribological properties, which means the BMG can be further optimized for the application of tribology by annealing regulation.
